1 Claim. (01. 101-381) My present invention relates to hand printing Figs. 7 and 8 are perspective and end elevation stamps and among the several objects compreviews, respectively, of an adapter provided for hended thereby the principal one is to provide a use with holders differing in size from those preform of stamp for use in large offices or business viously illustrated.

I have devised a form of base and means for in- In carrying out my invention, I provide a base 10 terchangeably mounting thereon the printing l which is manipulated by a handle 2. The lower 10 surfaces or type blocks which are desired for a face 3 of the base is a horizontal surface prefergroup arrangement or which may be selected ably at right angles to the axis of the handle 2. for their associated use. At one side of the face 2, as shown in Fig. 1, or

A feature of my invention resides in making at each side thereof, as shown in Fig. 2, the base a holder which will accommodate two or more has an angularly disposed face, or faces 4 and 5, 15 type impression surfaces so mounted that the use extending upwardly and laterally, preferably at of one will not interfere or mar the impression angles of 45 degrees which I have found to be made by another and a form of code marking most serviceable in practice.

Generally stated, I tion comprise the means employed for detachemploy guide members permanently attached to ably mounting the type blocks on the holder by faces 3, 4 and 5 and adapted to detachably engage the use of guides on the latter and a specially the holders in which the printing blocks or mem- 5 designed clip, cooperating with said mounting bers are permanently secured. for securing the printing surfaces and pads, The guide members are formed of sheet mawhich is so formed that a space is provided on terial and comprise a bottom 6, the edges of the back to receive a label which is of the same which are turned upwardly and inwardly at 1 and size and preferably an impression of the type 8 to form guideways. At one end a portion of 30 block itself, the structure of the holder being the bottom 6 is upset as indicated by 9 to form shaped especially to protect the label against a stop. These members are rigidly secured to injury. the faces of the base by screws lfl as shown in To these and other ends my invention con- Fig. 6.

This arrangement provides 55 for the mounting of an identifying label l3 which is adequately protected against abrasion. The holder further comprises the side walls I l and I5 extending outwardly from the inner edges of a pair of stifiening webs which are provided by reason of the fact that the guide rails II and 12 are bent back on themselves. In Fig. 3, I have shown the side walls as provided at their outer edges with inwardly extending teeth or serrations which by slightly compressing said walls will become embedded in the stamp-carrying pad which is usually made of sponge rubber. However, if the stamp-carrying pad is of a form intended to be vulcanized to the holder, the inturned edges of the side walls may be smooth, as shown in Fig. 5, and the bottom it! provided with fingers I 6, formed as shown, and adapted to form anchors for the printing block.

The insertion of the printing block holder in the guideway and of its attaching member is illustrated in Fig. 6, its inward movement being limited by the stop 9. As it is desirous that a tight fit be maintained between the guides on one of these parts and the rails on the other, I provide the bottom it? of the holder with an aperture l0 at its outer end for the reception of at removing instrument such as the key shown in Fig. 9 having a finger ring 2 and an engaging end 25. The apertures lil also furnish a convenient means for suspending the holders of printing stamps not required for immediate use upon hooks of a filing rack or cabinet. When so suspended the labels l3 will be outermost and as they are impressions of their corresponding stamps and as such read from left to right the identification of the stamps is facilitated and a new selection or assembly may be made quickly.

Since it often arises in practice that in a combination set of stamps one of them may have smaller type, making it desirable therefore to mount it in a narrower holder, I provide an adapter constructed as shown in Figs, '7 and 8 which at its outer edges has the rails il-IB fit ting the guideways 7 and 8 of the attaching member 6 and recessed at the center to provide additional guideways l 8 to accommodate the narrower stamp block holder, as will be understood. This adapter has a stop projection W at one end, corresponding to stop 9 on member 6 and an aperture 26 to receive the key or extractor shown in Fig. 9.

Certain uses call for a wide variety of rubber stamps and in many classes of work these are divided into sets according to the classification of the paper being handled and it is important to the user that he be able to quickly identify them and to this end I have adopted a scheme of coding the assembly by the selection of two or more colors applied either to the stamp bases or their handles 2 or both the bases and handles. When certain desired impression surfaces required for a particular job, such as the marking of a given class or set of papers have been selected and attached to the base i in the order of their intended use, the user is aware of his selection and by the association of each with particular color he can instantly locate among a variety of other stamps the one he particularly desires by the combination of colors on the handle 2. In Fig. 1 the stamp base carries two impression surfaces and its handle is painted with two contrasting colors, for instance, red in the crown area 2| and black in the stem area 22. Again in Fig. 2 when the base carries three impression surfaces, I have depicted for such use a third color, such as orange as indicated by 23.

The various features of my invention lend themselves admirably to the commercial manufacture of hand printing stamps, rubber stamps as they are frequently called. The bases I may be maintained in stock sizes with the attaching member 6 applied to their several working faces. Also the holders may be carried in stock with the rubber cushions afiixed thereto in readiness to have cemented thereon the impression surface or type which will be made up or molded in accordance with the specification of a given purchase order. The handles 7'; may be finished in a series of sets of colors so that when a completely new combination rubber stamp is required a handle having an appropriate color combination may be selected and secured to the stamp base.

What is claimed is:

A hand printing stamp comprising a base support presenting a relatively flat surface, a relatively fiat sheet-metal guide member carried on said relatively flat surface and including a relatively fiat bottom having at its longitudinal margins upwardly and inwardly extending guideways arranged in a parallel relation and extending lengthwise of said relatively flat, surface, a printing pad holder adapted to be slid into and out of printing position on said guide member and including a bottom having at its longitudinal margins outwardly and downwardly extending rails shaped complementary with respect to said guideways and serving to maintain the bottom of said holder in a spaced relation to the bottom of said guide member when said holder is positioned on said guide member in printing position, said rails being turned back on themselves so as to provide a pair of stiffening webs, said stiffening webs terminating in upwardly extending side walls disposed in a parallel relation and extending lengthwise of said holder and adapted to receive therebetween a printing pad.
